Embodiment Construction

[0024] Such as figure 1 Shown, the present invention comprises the following steps:

[0025] a. Support the floor formwork 1, set the wires on the floor formwork 1, determine the position of the box formwork 2, the position of the water and electricity pipeline and the position of the hole.

[0026] b. Spread anti-crack steel wire mesh 3 on the floor formwork 1 .

[0027] c. Bind the box form side rib beam on the floor formwork 1. The side rib beam includes the rib beam stirrup 4, the rib beam upper steel bar 5 and the rib beam lower steel bar 6, and the rib beam upper steel bar 5 and the rib beam lower steel bar 6 are connected Inside the rib beam stirrup 4.

[0028] d. Lay embedded pipelines.

[0029] e. Place pads 7 between the side rib beams of the box form and the floor formwork 1, use iron wire 10 to pass through the floor formwork 1, and fix the side rib beams of the box form and the keel 8 of the floor formwork 1 together.

[0030] f. Install the box formwork 2 in ...

Abstract

The invention relates to a construction method for a large cavity hollow floor slab. The invention transfers the buoyancy generated by a box mold during pouring and vibrating to a formwork system through floor steel bars, box mold side rib beams, iron wires and formwork keels to form an anti-floating point. By setting the box mold as an inner mold that can replace a template to be erected, the filling and vibrating can be seen during concrete pouring, which can ensure the quality of pouring and vibrating. Through the anti-floating design, the box mold is fixed to prevent the box mold from floating and displacement during pouring and vibrating, thereby ensuring the quality of concrete pouring and vibrating. The construction method provided by the invention is especially suitable for the construction of large-cavity hollow floor slabs, and can solve the problems of inconvenience of large-cavity formwork and easy vibration leakage during concrete pouring to be unable to guarantee the quality.

Description

technical field [0001] The invention relates to a floor slab construction method, in particular to a large-cavity hollow-core floor slab construction method. Background technique [0002] The cast-in-place hollow slab structure can save the amount of concrete, reduce the self-weight of the structure, reduce the amount of concrete and steel bars in the building as a whole, and reduce the overall cost. The closed cavity formed by the cast-in-place hollow floor slab reduces the transmission of noise and heat energy up and down the floor slab, improves the sound insulation and heat insulation performance of the floor slab, and brings good economic benefits due to the saving of building materials and the convenience of construction. In the future development of the industry, this kind of floor system will have a relatively broad application prospect. [0003] However, with the increase of the cavity of the hollow slab, the difficulty of construction increases, especially there a...
